BUTTON-DRILLING MACHINE.

SPECIFICATION f; ing part of Letters Patent No. 699,663, dated May 13, 1902. Application filed December 20, 1901. Serial No. 86,705. (No model.)

To alt whom itvrtcty concern:

Be itknown that I, ALBERT ALFRED CoYLn, a citizen of the United States, residing at Dubuque, in the county of Dubuque and State of Iowa, have invented a new and useful Button-Drilling Machine, of which the following is a specification.

My invention relates to certain improvements in button-drilling machines, and has for its principal object to constructa machine which will automatically drill and deliver the buttons and in its operation will not require the employment of highly-skilled labor.

A further object of the invention is to improve, simplify, and cheapen the construction of such machines andto provide for the adjustment of the parts for the production of buttons of different sizes and character.

WVith these and other objects in view the invention consists in the novel construction and combination of parts hereinafter described,illustrated in the accompanying drawings, and particularly pointed out in the appended claims.

In the drawings, Figure lis a side elevation of a button-drilling machine constructed and arranged in accordance with my invention. Fig. 2 is a plan view of the same. Fig; 3 is an end elevation of the machine. Fig. 4 is a sectional elevation of the same on line 4 4 of Fig. 2. Fig. 5 is a longitudinal sectional elevation of one of the button-chucks and its operating mechanism. Fig. 6 is a similar view of one of the drill-chucks and its mechanism. Fig. 7 is a transverse sectional elevation of a portion of the machine on the line 7 7 of-Fig.4. Fig. Sis an enlarged View of one of the buttons, showing the arrangement of the holes drilled therein.

Similarnumerals of reference are employed to designate corresponding parts throughout the several figures of the drawings.

1O designates a shaft journaled in suitable bearings 11 12 and carrying a pair of disks 13 14, which are intermittently revolved to present the buttons in proper position to be drilled. In each disk are formed eight openings 15, through which pass hollow spindles 16, in which are supported chuck-shafts 17, the inner ends of the latter being provided with split button-holding chucks '18 of the usual character, having the rear portionsof the the heads tapered, as at 19, and adapted to a suitably-shaped opening formed in the ends of the hollow spindle 16. The outer end of each chuck-shaft 17 is provided with a flange 20, between which and the adjacent end of the spindle 16 is a helical compression-spring 21, which normally keeps the chuck in closed position by retaining the tapered portion 19 within the openingin the end ofthespindle 16.

On each of the spindles 16 is secured a pinion 22, each pinion being of the same size and all intermeshing in a. continuous circular train, so that motion imparted to one of them will effect an equal rotative movement of each of the spindles. On two diametrically opposed spindles are arranged spur-gears 24, adapted to intermesh with a spur-gear 25, the iatter being rigidly secured to the journal 11 and effecting a rotative movement of the gears 24: each time the spindles of the latter are traveled by the intermittent movement of the supporting-disks 13 and 14.

To the outer end of the shaft is secured a spur-gear 26, which receives an intermittent rotative movement from a mutilatedgear 27, mounted on a continuously-rotated shaft 28, which extends in a line parallel with the shaft 10. The mutilated gear 27 has four sets of teeth, three of which, 29,. are arranged in groups and when intermeshing with the spur-gear 26 impart a movement to the latter through an arc of ninety degrees, eifecting the turning of the shaft 10 and the disks 13 and 14 to the extent of a quarter of a revolution. The remaining tooth of the gear 27 is adapted to effect a movement of the spurgear 26 to the extent of one-eighth of a revolution, so that each complete revolution of the gear27 will effect a movementof the disks,

13 and 14. through an angular distance equal to seven-eighths of a revolution.

On the periphery of the disk 14 are a series of notches 31, with which may engage a locking-dog 32, normally held in the locking position by a suitable spring 33. On the shaft 28 is arranged a cam 34, adapted to operate on the dog 32 and move the same from engagement with the notches 31 immediately preceding the engagement ofeach of the sets of teeth on the mutilatedgear with theteeth of the spur-gear 26. The camis so constructed as to prevent the return of thedog to locking position until after the disk 14 has moved to an extent greater than an eighth of a revolution after each movement or operation of the gear-teeth 29, but has one shorter face 35, which will permitthe movement of the pawl to locking position after the one-eighth revolution imparted by the gear-tooth 30, so

that the disks 13 and 14 will first be moved disks.

through three successive quarter-revolutions and locked in position and then through an eighth'revolution and locked in position.

40 41 designate two disks secured on a shaft 42, mounted in bearings 12 and 43, the shaft receiving a reciprocating movement only, and this movement being imparted at regular intervals from a crank 45 on a primary shaft 46, which is held in bearings 47 and receives motion in any desired manner from any suitable source of power. The two disks 40 and 41 have depending portions 48, in the lower edges of which are formed slots 49, adapted to guiding-bars 50 on the bed or frame of the machine to prevent any rotative movement of said disks. In each of the disks 40 and 41 are formed a series of slots 51, elongated on a line concentric with the periphery of the disk to permit of the angular adjustment of chuck-shafts 52, which extend through the slots in alining-bearings in suitable bushings 53, held in blocks 54 on the outer faces of the The blocks are arranged on lines extending in a substantially radial direction from the center of the disk and are rigidly secured to said disks by set-screws 55, passing through suitable radial slots 56 in said blocks and thence into a threaded opening tapped in the disk. This construction permits of an adjustment in two directions of the chuck-shaft and enables the operator to set said shaft in such manner as to present the drills to the proper point on the button, the adjustment being such that of the four drills 57 each will operate to drill a hole in a separate button, but in a different position in each button. Each of the drill-shafts is provided with a suitable pulley 58, around which may extend asingle driving-belt. On the driving-shaft 46 is a bevel-pinion 59, engaging With a bevel gear-wheel '60, the proportions of the gears being such that four revolutions of the shaft 46 will impart one revolution to the bevel-gear 60 and the shaft 28, to which it is secured, each quarter-revolution of the shaft 28 resulting in a change in position of the button-holding chucks and each revolution of the shaft 46 effecting a movement of the four drills toward and from the button.

To the fixed frame of the machine is pivoted a chuck-opening lever 61, having one end adapted to come into contact with the outer ends of the button-chuck shafts 17, its opposite end being connected by a rod 62 to a pivoted. lever 63, arranged adjacent to the main shaft 46 and receiving motion at each revolution of the shaft from a wrist-pin 64, carried by a suitable disk 65 on the shaft.

In the operation of the machinemotion is imparted to the shaft 46 from any suitable source of power, this motion being transmitted to the bevel-gears 59 and 60, to the shaft 28, and thence to the mutilated gear 27, to the shaft 10, and disks 13 and 14, the latter receiving an intermittent movement. Supposing all of the button-chucks to be supplied with blanks and the first of the sets of teeth 29 be just starting into engagement with the spur-gear 26, the cam 34 has unlocked the dog 32 and the spur-gear 26 receives a movement to the extent of one-quarter of a revolution. This movement is imparted to the disks 13 and 14 and to all of the spindles 16 and chuck-shafts 17. The gears 24 by intermeshing with the stationary spur-gear on the journal 11 are also moved to the extent of one-quarter, and this movement is transmitted to all of the spindles 16 through the medium of the connected train of pinions 22, thus turning the button-blanks to proper position for action by the drills. The dog 32 then locks in one of the notches in the disk 14, and thedrill-spindles are moved against the button-blanks and then retracted after each drilling a single hole in one of four of the blanks. This operation is repeated three times until the three sets of teeth 29 have operated, after which a single tooth 30 moves the shaft 10 and the disks through one-eighth of a revolution, so as to bring the intermediate sets of chucks into alinement with the drill, the first drilling movement taking place in each blank immediately after the single tooth is operated and the four holes being drilled and the blank discharged by the operation of the chuck-operating lever 61 after the last of the sets of teeth 29 are operated. At each movement of the disks ablank is discharged, and the operator inserts a fresh blank While the chuck is still open, this being all the Work necessary on the part of the operator and the machine carrying out the rest of the operation and discharging the finished button automatically.

While the construction herein described and illustrated in the accompanying drawings presents the preferred form of the device, it is obvious that many changes may be made in the form, proportions, size, and minor details of the structure without departing from the spirit or sacrificing any of the advantages of my invention.
